IMPROVEMENT IN MACHINES FOR MAKING PAPER CYLINDERS.

Specification forming part of Letters Patent No. I 76,344, dated April 18, 1876 application filed September 23, 1875.

To all whom it may concern Be it known that I, CHARLES O. PERRINE, of the city of Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Machines for Making Paper Cylinders, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal section, and Fig. 2 a cross-section; Fig. 3, an elevation of the upper portion of the outer cylinder Fig. 4, an elevation of the lower portion of the inner cylinder.

The nature of this invention consists in constructing one or more revolving wire-gauze cylinders around a central feed pipe, for the purpose of forming paper cylinders from paper-stock 011 the interior of the wire-gauze.

In the drawings, A represents the outer cylinder, made of wire and having coarse meshes; B, the interior cylinder, made of finer wire and having finer meshes than the cylinder A; C, the stationary central feedpipe; D, the shoulder or stop on the feed-pipe C for adjusting the same; E, the slot or opening in the feed-pipe C through which the pulp or paper-stock passes; F, the cylindrical axle or tube G, the head by which the woven-wire cylinders are attached to the axle F; H, the bands at the ends of the in terior cylinder B I, the bands at the ends of the outer cylinder A J, the connecting rods or bars.

The outer cylinder A is made of heavy woven-wire fabric, and its form is maintained by the bands I. This cylinder is attached to the head G, by which it is connected to the axle F, which is hollow or cylindrical. This axle F is to be provided with suitable bearings; and to this axle power is' to be applied by means of any suitable pulley or gearing, to give the cylinder A a rapid rotary movement. Into the hollow axle F the end of the stationary feed-pipe C is inserted, as shown, so that the collar D comes in contact with the head G. This feed-pipe is provided with an opening, E, or a series of holes running the entire length of the gauze cylinders.

In order to give the necessary strength, and to be able to withdraw the paper cylinders when formed, an interior cylinder, B, is provided, which cylinder is made of finer wire and meshes than the cylinder A, and which rests against and is supported by the outer cylinder. A number of these cylinders B may be provided, so that while one is withdrawn another can be inserted, so as to keep the machine in continuous operation. If desired, a sutficient number of such cylinders can be used to allow the paper cylinders to remain in them until thoroughly dried. If not so desired, the interior cylinders B should be so made as to open or yield, so that they can be drawn off over the paper cylinders when they are drawn from the main cylinder A, and used again.

It will be found useful to provide several feed-pipes, C, of different sizes, so that the feed may be adjusted according to the quality of pulp or rapidity of movement of the cylinders.

By giving the woven-wire cylinders A B a rapid movement the centrifugal force expels the water and a sufficient portion of the moisture to form the paper cylinders sufficiently dry to be handled after being taken from the interior gauze cylinder B, and sufficiently hard to be placed in suitable heating and calender rollers, and finished immediately.

The pulp is fed through the hollow axle F, either direct or by the application of a nonrotating tube inserted within the axle sufiiciently far to meet the feed-pipe C. This pipe, which connects the apparatus with the tank containing the pulp, will be furnished with a cut-0E valve, by which the flow of the pulp can be adjusted or entirely cut off, as desired.

This machine may be made of any size to produce cylinders of paper of any desired length or diameter.

In place of the cylinder B, a sheet of wire cloth may be used by. simply rolling it into shape, and placing it inside of the: main cylinder; and it is obvious that the feed-pipe C may be used from the other or open end of the cylinder, in which case the axle may be solid.

The outer cylinder A may be made of castiron or other suitable material, provided with suitable apertures or other means for the exit of the water.

What I claim as new, and desire to secure combination with the cylinder A and central by Letters Patent, is as follows: feed-pipe (J, substantially as and for the pur- CHARLES O. PERRINE.
